Much has been said about marketing software. At the same time, there are still no common ideas about what particular functions should it do and what tasks it should solve. The history of the development of software products for marketing services is closely related to the development of marketing in the United States. It can even be argued that the software products offered to marketers directly reflected the state of marketing in the United States at one time or another. I decided that it is impossible to write an article on such a topic without preparation and surched the Internet to see what others were writing about it. And in fact, I am almost disappointed. Why? Particulary, because much has been written about software, I would even say, very much and in some detail.

In order not to dupe other authors, this article will be written in a slightly different way.
